Current TCP is not able to distinguish corruption losses from packet loss events. Hence, high transmission errors and varying inherent latency within a wireless network would cause seriously adverse effects to TCP performance. To improve TCP in IEEE 802.11 multi-hop ad hoc wireless networks, this study proposes an error recovery mechanism based on coordination of TCP and IEEE 802.11 MAC protocols. The simulation results confirm that the proposed error recovery approach could provide a more efficient solution for frequent transmission losses, and enable TCP to distinguish between congestion errors and transmission errors, and thus, to respond with proper remedial actions.
